This is the map of the denominational profile of Hungarians in counties Maramureș / Máramaros and Satu Mare / Sătmar / Szatmár ( see list ), referring only to the relative weight of Hungarian denominations and to communities with at least 10% Hungarians. In these areas there is a balance between Roman Catholics and Reformed. In general, the Reformed denomination signals here too the presence of an older Hungarian population. In the lowland area of Sătmar / Szatmár the Hungarian Roman Catholics are generally Magyarised Swabians or the result of the denominational assimilation they produced. The Hungarian population of the mining settlements ( especially in the gold-mining region in the Sătmar highland, i.e. Baia Mare / Nagybánya and its environs, but also the copper-mining settlement Băile Borșa / Borsabánya or the salt mines in Ocna Șugatag / Aknasugatag and Coștiui / Rónaszék ) is overwhelmingly Catholic, to a great extent as a result of colonisations during the Habsburg period. These used to result most often in new industrial settlements with a Catholic population brought from various Habsburg states and ethnically diverse, but to a great extent German-speaking, later on assimilated to the Hungarian ethnic group. Some Roman Catholics can be simply the direct result of the 18th-c. Counter-Reformation. In the lowland area of Sătmar / Szatmár, next to the border with Hungary, there is also a significant Greek Catholic Hungarian population, the result of 19th- and 20th-c. Magyarisation.
